Upgrade! New version

In response to the shortcomings of the first version, we have made improvements. Now the piston is more sensitive, the oil circuit design is more balanced, and we have also reduced the price by reduce unnecessary design.

The new version uses metal pads and normal disc as standard setting . if you still want floating rotor please jump to new version link to check.

140 and 160 compatible

In the new version, we have redesigned the appearance so that it can be compatible with 140 and 160 at the same time by the same adapter

what's the different between old and new ?

The new version is an improved version of the old, which mainly optimizes the piston and oil circuit design. Changed to metal pads, no heat sink, because it is not needed, the metal pads have strong resistance to heat, and the disc is changed to a more cost-effective style , Of course if you need luxury configuration, please check another link of ztto official store. the new version use DB1 brake pads, the old one use m8000 pads.

Sometimes we receive some questions like this : Is it hydraulic or mechanical?

Both. The brake is filled with mineral oil. brake wire pulls the main piston, and the main piston hydraulically drives the two sub-pistons.

Don't worry about the piston

Yes, we have noticed that some buyer say that only one side of the piston will move. I think we need to explain something. (unexpectedly that so many road bikers use hydraulic disc brakes for the first time), this is very common for hydraulic disc brakes, No matter it is an MTB or a road bike brake, no matter how advanced or expensive your brakes are, all hydraulic brake systems and even vehicle brake systems will have such things happen, but at the same time it is very easy to solve.
In general, you just need to hold the moving side, which will make the lazy side move, and then give the piston a little lubrication. Repeat a few times. It only takes one minute to solve this problem.
A famous blue tool brand has a video to teach you how to solve it, but we can't write a link here due to copyright reasons. You can search by yourself or contact us to get the video link. So don't worry, these brake working good .
